The person spoke to The Associated Press on condition of anonymity on Friday because there has been no announcement about the specific nature of Armstead's injury. Analysis: The 6-foot-5, 304 pound Armstead is in the first year of a five-year, $65 million extension that he signed before the 2016 season. He has been a starter since late in his rookie season in 2013. Leg injuries have hampered him for parts of the past two seasons.
